Featured Projects

Deep-dive implementations solving real-world marketing data challenges.

Server-Side GTM Cloudflare GTG

First-Party Tracking Pipeline & ITP Bypass

Problem: Apple's Safari ITP was enforcing a strict 24-hour cookie limit, instantly breaking multi-touch attribution for returning users.

Solution: Engineered a secure HTTP tracking architecture using Cloudflare Tag Gateway and Stape.io to bypass client-side JavaScript restrictions.

  • 2-Year Attribution Window Restored
  • Custom Subdomain CNAME Routing
  • HTTP-Only `Set-Cookie` Headers

Data Reconciliation Client Hints API

Ghost Transactions & Attribution Decay

Problem: Client-side tracking is bleeding data due to ad blockers, skewing executive dashboards.

Solution: Reconciled 50,000 backend server logs against front-end events to expose a 36% data loss, tracing the suppression back to specific privacy browsers.

  • Server vs. Client Database Reconciliation
  • SEC-CH-UA Parsing
  • Quantified $23M Missing Revenue Gap

Attribution BigQuery SQL

Last-Click Attribution Analysis

Problem: Default last-click reporting incorrectly credited $0 to every paid social channel.

Solution: Built a custom SQL attribution engine directly within the data warehouse, exposing a $412K misattribution error and mapping true TOFU performance.

  • Recursive SQL CTEs for Journey Mapping
  • Multi-Touch Linear & First-Click Models
  • Executive Misattribution Report

RevOps Identity Graph

GA4 & Salesforce Pipeline Reconciliation

Problem: Executives paused a $150k/month budget due to a severe data mismatch between Marketing (GA4) and Sales (CRM).

Solution: Engineered a deterministic SQL Identity Graph to connect raw web logs directly to CRM data, eliminating a massive Cartesian explosion error.

  • COALESCE() Logic for Disconnected Records
  • $7M in "Ghost" Pipeline Removed
  • 1,600 Untracked Leads Recovered
